"Alexei A. Frounze": > Sure BP and older versions of BC++ has no good optimizers (BP mostly). For BP I'd say there is no optimiser at all... (Well, it puts XOR AX,AX to zero AX, and simplifies some constant expressions computable at compile-time but that's all!) BTW there is a good overview of GCC optmisations at GNAT pages: http://www.act-europe.fr/act/texts/gnat_technology/gnat_gcc.htm (A copy @ http://www.gnat.com/texts/gnat_technology/gnat_gcc.htm ) ______________________________________________________ Gautier -- http://members.xoom.com/gdemont/gsoft.htm
